Please explain! Thanks!

The table shows 2002 General Social Survey data on family income and the subjects highest degree attained, for which X2 = 158.0 (P-value = 0.000). What is your conclusion for the chi-square test of association? There is a significant association between highest degree attained and family income at the (X = 0.05 level. There is not a significant association between highest degree attained and family income at the a = 0.05 level. Using 3 decimal places, estimate the difference between the lowest and highest education groups in the proportion who report ... ...below average income. 35.840 ...above average income. What is the relative risk of a below average income, comparing the lowest and highest education groups? Use 3 decimal places.

Solution

b) difference between the lowest and highest education group in the proportion who report

i) below average income = 50.50%-14.66% = 0.5050-0.1466 = 0.358

ii) above average income = 7.00%-42.23% = 0.700-0.4223= -0.352

c) The relative risk for below average income, comparing the lowest and highest education group = 0.5050/0.1466 = 3.445
